•are changes in an organisms DNA
Mitosis:Division of a parent cell, producing 2 identical daughter cells. (For growth and repair of body. Chromosome number remain the same in each cell.)
Metosis: 2 divisions of a germ cell, producing 4 non-identical gametes. (For genetic diversity in sexual reproduction. Chromosome reduce by half in each cell.)
Hope this helped, have a great day! :D
The cell organelle that is most likely malfunctioning in the patient's body cell is the LYSOSOME. In animals, including humans, lysosomes is responsible for destroying worn off organelles, removing wastes and protecting cells from invaders. If the lysosome is malfunctioning, wastes will not be remove from the cell and this will lead to build up of wastes.
In plant cells, the vacuole is responsible for removing wastes from the cell.
Answer:
Abiotic factors of ecosystem are the non-living component such as water, air and nutrients. If abiotic factors are changed, the ecosystem is disturbed because abiotic factors are very important components of ecosystem. Without these, the ecosystem will not perish or grow. If water is removed from an ecosystem, all the organisms will be die because every living organisms needs water for their survival. If nutrients are not available, the food produce by plants is less in quantity and animals which feed on plants die because of huger.
